IBM Redbooks Solution Guide
This IBM® Redbooks® Solution Guide provides an overview of IBM FlashSystem™ 820 integrated as
back-end storage with IBM Storwize® V7000.
IBM Storwize V7000 is a virtualized software-defined storage system that consolidates workloads for
simplicity of management, reduced cost, highly scalable capacity, performance, and high availability. This
system offers improved efficiency and flexibility with built-in flash memory and disk storage optimization,
thin provisioning, and nondisruptive migration from existing storage. IBM FlashSystem delivers
performance that is driven by IBM MicroLatency™ for quick response time, and is a durable, high reliability
enterprise class family of flash memory systems that are easy to integrate. FlashSystem uses IBM
Variable Stripe RAID™ and two-dimensional RAID technology to maintain performance, protect data
integrity, and preserve usable storage capacity.
IBM Storwize V7000 FlashSystem Edition enables you to accelerate your mid-range storage solution by
taking advantage of the performance and low latency of FlashSystem 820. Figure 1 shows IBM
FlashSystem 820 and IBM Storwize V7000 FlashSystem Edition.

Business value
Today, customers are challenged with the lack of solutions to manage the exponential growth in the
volume of structured and unstructured data, and with shrinking product cycles and a focus on top-line
growth. Customers are looking for infrastructure solutions that can be deployed rapidly, managed easily,
and that can run optimally without compromising reliability. In a 24x7 market, clients often strive to
achieve maximum performance that is coupled with deep features and functions, and this performance
must be delivered in a cost-effective manner.
I/O performance is critical for applications such as read-intensive databases, SAP, and virtual desktop
infrastructures (VDIs). Although you can improve performance by using faster processors and faster
systems, data must still be read from and written to storage. Traditional hard disk drive (HDD) storage
cannot provide the speed that is required by many applications. Many solid-state drive (SSD) solutions
add latency because software is required to manage access to flash memory. Using FlashSystem with
Storwize V7000 can increase storage performance as much as 2x.
FlashSystem 820 is energy efficient. Using FlashSystem storage with Storwize 7000 can provide a green
solution that decreases power use by as much as 50%. For details and ordering information for the IBM
Storwize V7000 FlashSystem Edition, see IBM US Announcement Letter - IBM FlashSystem 720 and IBM
FlashSystem 820, found at the following website:

4. Solution overview
This solution includes one FlashSystem 820 that is virtualized by Storwize V7000, providing the
performance of FlashSystem capacity with the advanced functions of the Storwize V7000.
When paired with Storwize V7000, FlashSystem inherits all the rich base system functions, including
Real-time Compression, FlashCopy, Easy Tier, and thin provisioning.
Solution architecture
IBM FlashSystem 820 supports Fibre Channel connections to Storwize V7000. You can attach
FlashSystem 820 to the rack Fibre Channel switch and gain the benefits of the V7000 functions by having
FlashSystem as Tier 0 storage and using the hard disk drive (HDD) disks that are contained in the V7000
enclosures to provide a tiered solution.
This solution architecture provides nondisruptive capacity scaling in two dimensions. Additional
FlashSystem 820 systems can be added to the solution as Tier 0 capacity to maintain high IOPS
performance. Additional Storwize V7000 expansion enclosures and HDD capacity can also be added to
the Storwize V7000 enclosures to add capacity that Easy Tier uses to intelligently move hot (frequently
accessed) data to FlashSystem capacity, and cooling (less frequently accessed) data to the HDD media
automatically.
Usage scenarios
There are many usage scenarios where IBM Storwize V7000 FlashSystem Edition is useful. Here are a
few such scenarios.
Accelerating databases
Most database applications are highly read-intensive. As such, additional processing power alone does
little or nothing to improve performance. By placing all read data on low latency flash memory, reads are
performed much faster, boosting database performance over conventional disk systems with no tuning or
changes to the code or system architecture.
IBM Storwize V7000 FlashSystem Edition has the following capabilities:



Decreases I/O wait time in enterprise workloads
Delivers the lowest latency available on any SAN platform
Accelerates commonly I/O-bound workloads, including transactional, batch, and complex analytics
SAP acceleration
Many SAP databases consume less than 2 TB of storage. SAP is pushing clients to accelerate
performance by adopting the High Performance Analytic Appliance (HANA) in-memory database
architecture. This adoption often leads to a significant rearchitecture of the entire SAP infrastructure,
which can lead to high costs and a risk of disruption in service delivery.
IBM Storwize V7000 FlashSystem Edition offers the following capabilities:

Eliminates I/O bottlenecks in enterprise SAP workloads

Provides the lowest latency of any SAN-based storage solution for time-sensitive workloads with IBM
MicroLatency

5. 
Enables a small, cost-effective pool of flash memory to deliver performance improvements

Supports a phased approach to HANA adoption by delivering consistently higher performance for
SAP NetWeaver Business Warehouse workloads with no rearchitecture required.
Accelerating virtual servers and VDI
Virtual servers and virtual desktop infrastructure push conventional storage systems to their performance
limits. The result is poor application response times and a bad customer experience. Virtualizing your
environment with IBM Storwize V7000 FlashSystem Edition results in drastically faster response times for
the most common virtualized applications. Couple this performance to the "log on" or "boot" storm and
make system usage productive again.
IBM Storwize V7000 FlashSystem can offer the following capabilities:




Virtualizes databases without performance loss
Eliminates I/O density and hot-spot issues that are common to highly virtualized environments
Controls and mitigates ‘log on’ or ‘boot’ storm performance issues
Delivers storage consolidation without sacrificing performance
